To all inkom it may concern:

lBe it known that I, Fonns'r V. lDJe'rWILnR.,V a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have invented .certain newand useful Improvements in Cooking Apparatus, of which the following is a specification. 1

'llhis invention relates to improvements in cooking apparatus designed for the use of fiuid fuel and one of the objects of the invention is to provide an improved portable device of this character, having means whereby the different cooking operations may be simultaneously performed in dif ferent parts of the apparatus, by the heat from a single burner, 'and means whereby the 'burner may be shifted to be used for broiling.

A further object is to provide an4 improved device of this character having a pluralityv of stove holes and means whereby the heated *uted to the stove holes. y

Tofthe attainment of these ends, and the air from the burner will equally distribaccomplishment of other new and useful objects as will appear, the invention consists in the features of `novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention, and in which:

Figure 1 is a perspectlve view of an 1mproved apparatus of this character con` structed 'in accordance with the principles of this invention. o

Fig. 7 is a horizontal sectional viewtaken on line 7--7, Fig. 5.

Referring more particularly to the draw# (A ings Vand in the preferred form .of the invention, the base of the apparatus 1s hollow and forth. These walls, with the exception of Specioation of Lettera Patent. ,Patented time 25, Imlld. 1 Application-med March 30, 1914!. Serial No. @2&135.

the extending portion of therear wall, are y preferably insulated to prevent loss of heat and to conserve the heat within the base.v 'Ihe base of the apparatus may be of anyI lengthwise `of the base, the forward edge' thereof abutting the inner face of the front wall 12 on opposite sides of the door open` ing 18 which latter is closed by a suitable closure or door 19, the door opening being "arranged preferably to extend to the base l0.

parts are securedv Will ' Another partition 20 is arranged in the base preferably adjacent the rear wall 13 thereof so as to limit the depth of the chamber formed by the partitions 17, and a cover 21 extends over the space formed by the partition 20 and the adjacent wall 13 as well as the partitions 17 to prevent the heated air from entering such space and in which space the heat units would be lost.

'Ihese partitions 17 extend from the bottom 10 of the base and preferably termi` nate short `of the top 22', which latter rests upon the walls of the base and is secured in` position in any suitable manner. The top 22 is provided with stove holes 23 therethrough and depending from the lower face of the top are Hanges 24, 25 which coperate with the partitions 17 to form the burner space or chamber. `'llhe partitions 25 are preferably rounded or curved as shown to prevent the heated air and gases from entering the' corners at the front of the base,

t while the partitions24 are arranged so that they will converge from the sides of the base, at points adjacent the forward extremity thereof toward the rear of the base for directing the products of' combustion and heated air in the base Vto the outlets 26, 27. A damper or valve 28 may be provided for controlling the outlet 27 ict 'Ihe partitions 17 areA preferably formed of sheet material and are bent so as to form flanges arranged at the top and the bottom thereof, the lower Hanges rest upon the base 10, while the uppermost flanges serve as supports for horizontal partition members 29,

and iipon these fianges also rest the lower extremities of the flanges 24, 25. The partitions 17 are also preferably shaped to form a support 30 upon which another horizontal partition 31 rests, and a spacing member 32 1s arranged between the partition' members 29, 31 for holding them spaced, and this spacing member may be secured to the respective sides 11, of the base for holding the partitions 29, 31 in position. Insulating material 33 is provided for the spaces between the partitions 29, 31 and the top 22. The partitions 17 may also be provided with inwardly projecting portions 34, to form a guide way beneath which a removable tray -35 stands and which tray is ada ted t0 be inserted into the base through t e door opening 18,'to rest upon the bottom 10 thereof, the insertion of the tray 35 being limited by the partition 20.

A burner 36 of any desired configuration is arranged within the burner space or chamber thus formed and this burner is mounted in such a 'manner that it will be spaced above the tray 35 suiliciently to permit it to be rotated, so that the heated air or products of combustion therefrom may be directed to the stove holes 23 or to the trai'y 35.

l n order to equally distribute the roducts of combustion to all of the stove `l'ioles, there is provided a deieetor 37 which is preferably detachably connected to the top 22 of the base to depend therefrom and is of a configuration to extend over a considerable area of the under face of the top of the base between the stove holes. rlhe body of the deflector 37 tapers from the top 22 to a point above and in close proximity to the burner 36, sol that when the burner is lighted, the flame will strike the deflector, which also acts as a spreader, and 4will direct the flame and products of combustion to the stove holes. The spreader plate also serves to strengthen the top plate of the base and holds it against warping. In order to support combustion, air openings 39 may be provided in the side walls 11 and similar air openings 40 are provided in the partition 17, so that air entering the openings 39 will pass intoA the chamber 41 formed by the partitions 17 and side walls and a horizontal partition 31 and the base 10, and from these chambers will pass through the openings 40 into the burner space.

Arranged a suitable distance above the base of the apparatus and supported by the extension of the rear wall 13, and upri hts 42 arranged at the sides of the base, an at the rear thereof, is an oven designated enerally by the reference numeral 43, w ichv extends only a short distance over the base from the rear thereof. A partition 44 is 'arranged between the luprights 42 and is spaced from and arranged parallel with the the bottom 45 of the oven. Uprights 46 are arranged between the partition 44 and the extension of the back 13 above the base, to form a flue, and which flue has communication with the outlet opening 26 inl the top of the base. The bottom of the oven is rovided with an inlet opening 47 from w ich a tapering Hue 48 depends, and which tapering ilue is provided with a iange portion 49 adapted to be inserted into the flue 47, so thatr when the damper 50 in the flue 57 is opened, the heated ases will pass from the base into the flue 4 to be dischar ed into the oven 43 below the bottom 51 of t e comment, and a similar passage 56 is arranged at the rear of the oven compartment and communicates with the passages 55. Thus it will -be seen that when the heated air is discharged from the ue 47 into the oven it will be prevented from passing into the assage 56 by the deflector 52, and wil be caused to flow about the compartment in the oven and into the passage 56 from where it will pass out of the outlet openin 57 when the damper 58 is opened. A portion of the heated a1r will also pass into theoven compartment through the openings 59 in the walls 53 thereof. Obviously supports 60 may be provided in the oven compartment.

In order to permit the burner to be rotated, any suitable connection may be provided between the burner and the gas supply tube 61. For this purpose, a portion of the burner projects through a suitable bearing 62 in one of the side walls of the base and is provided with a cup or chamber portion 63 having a closed extremity 64 pro-l vided with an opening therethrough having a flange 65 therearound. A tube 66 having a valve 67 therein, and which tube telescopes with the tube 61, projects into the cup 63 through the opening 64, and in order to support the tube 66, a suitable sup ort 68 may be provided and through which the tube passes. gas will be discharged into the cup 63 and will iow from there to the burner. The burner is adapted to be reversed by means of a handle 69 connected with the cup 63, and the bracket 68 is so shaped that it will coperate with the handle 69 to limit the degree of rotation of the burner and to assure its proper positioning.

Obviously the oven is provided with a suitable door o ening having the usual door or closure 70 t erefor.

Thus it will be seen that the .1

27 is closed and the damper 50 is opened.- ln this event the heated gases or products of combustion after being circulated across the stove holes will pass through the flue 47 to the oven, and the temperature of the oven can be regulated by the damper 58.

When it is desired to .broil or toast, the

`damper 50 is closed as are also the stove holes, the burner is then reversed to direct the products of combustion to the tray or broiler, and the damper 28 may be opened to permit the products of combustion to pass therethrough.
